Any advice? How can I handle it?

Hello,
I'm really struggling with not being able to conceive and starting counselling next week. How do you cope? It's so hard finding enjoyment in anything, as all I want to do is have a child and be a mum. I have no interest in socialising, exercising or doing anything that would usually bring me happiness. Luckily work keeps me busy 9-5 on weekdays but I find evenings and weekends really hard where I'm lonely and depressed. I end up just going to bed early to waste the days away.
I feel I can't keep living like this, it's wasting years of my life being depressed and miserable. I don't like to socialise as everyone else is moving on with their lives and want to be surrounded by positive/happy people rather than someone who's depressed and doom & gloom. Most of the family know about our fertility struggle as I told my mum who told other family members, and I've ended up crying when asked the baby question so I've had to let others know. People knowing doesn't really help, as although they know why I'm depressed, they don't change their behaviour so they still talk about the subject which hurts.
I feel my life is on hold where I can't plan anything in advance i.e. holidays as you can't fly after you're so many weeks pregnant, and will be unwell in the first trimenster, my career is impacted where I want to qualify for maternity leave and pay, I can't drink, consume caffeine, use hot tubs, do strenuous exercise etc. I'm just so fed up of it all and want it to be over.
Just had to get this off my chest xx
